Other Notes: "A masterpiece of efficient circuit design, the ST-70 provided reliable, high-quality audio amplification at an affordable price. The popularity of the ST-70 contributed more than any other single product to continuing consumer interest in tube-based stereo amplifiers at a time of increasing market dominance by solid state audio products. Because of its excellent value for cost, Dynaco tube amplifiers were often referred to as “the poor man’s McIntosh.” More than 350,000 ST-70 amplifiers had been sold when production finally ceased, making the ST-70 the most popular tube power amplifier ever made." - Audiophile Nirvana
